3.4.2 Short circuit/overload at an output module

Deleting procedure

S Set all outputs of the output module to logic

"0" (RESET)

S briefly interrupt the CP connection at the CP

output module

S briefly interrupt the operating voltage of the

CP system at the field bus node

3-18

If there is a short circuit or overload:

–

all digital outputs of the module will be switched off,

–

the green LED "Diag" on the output module will flash

quickly,

–

the bit short circuit/overload of the diagnostic byte will be

set to "logic 1" (SC/O).

Please note

The outputs cannot be used again until the short circuit or

overload is eliminated and the fault is deleted.

Deleting faults

You can delete a fault by resetting all eight outputs. You can

do this as follows:

Explanation

– Manually or automatically in the program

– Outputs on the output module are reset auto-

matically

– All outputs of the CP system are reset auto-

matically

The outputs can then be set at "logic 1" again.

If the short circuit still exists, the outputs will be switched off

again.
